Porn star Julian St. Jox has sensationally claimed that he engaged in a three way orgy with Kim Kardashian and another female porn star, Emily Ann over a decade ago at an Los Angeles party.

The shocking allegations reportedly took place when the star was 20 and married to first husband, music producer Damon Thomas.

Julian reportedly told Star magazine that though she wasn't famous he was instantly interested in her: "She was wearing a tight miniskirt and tank top and designer shoes and bag," he remembered.

"From afar she looked gorgeous. She had a great body and seemed bright … [she] something special about her: a je ne sais quoi."

In the interview the porn star goes into graphic details about the encounter claiming that Kim received oral sex from Emily Ann and was clearly “enjoying herself” as the three cavorted in a back room together at the alleged swingers party.

He claimed, she "looked like she was enjoying herself very much,” as he had sex with her.

"She was a little submissive, but she was good," he recalled. "She knew what she was doing. She was very responsive to me."

The story has been strenuously denied by Kim Kardashian's camp according to RadarOnline.

RadarOnline also claimed that a second source confirmed that the story is true.
